How much of SNSF-funded research is related to artificial intelligence?

17.07.2025

SNSF-funded research related to AI increased significantly between 2011 and 2024. By applying an approach using key terms to identify AI-related grants, we could illustrate the methods preferred by the different research domains.

It comes as no surprise that AI-related research has increased across the board. Headlines today would lead one to believe that almost all projects involve AI. The reality is more nuanced. To put things in perspective, this story first defines what is meant by AI-related research before quantifying the extent of its usage in grants awarded by the SNSF over the last 14 years.

While the development of AI is typically attributed to disciplines in the mathematics, informatics, natural sciences and technology (MINT) domain, studies report a widespread adoption of AI methods across all scientific disciplines.1 This has furthermore motivated investigations into the societal impact of AI. The second half of the story breaks down the different applications of AI preferred by the three research domains based on the most repeated key terms over time.

Textual analysis of funded grants provides a potential basis for understanding the role AI plays in SNSF-funded research. To do so, we applied a transparent and reproducible strategy using key terms to identify AI-related research. While some AI-related grants develop AI systems or techniques, others apply AI methods to answer research questions. A third category investigates the impact of AI on society without necessarily using or developing these methods.

Shaping the future of research is one of the SNSF’s strategic priorities. This search of key terms will serve as one basis for broader discussions on the effects that AI is having both on research itself and on research funding policy.

Some key concepts of artificial intelligence

To identify AI-related research in SNSF-funded projects based on their titles, keywords and summaries, we used a list of key terms (Table 1) published in a bibliometric analysis conducted by the European Commission;4 however, we adapted the methodology. We identified some ambiguous terms that can refer to an AI-related concept but not exclusively (e.g. “neural net*” may also refer to a biological neural network, and “face detection” may refer to the human ability to detect a face). If a grant included one of these ambiguous terms, we required the presence of a second term to classify the grant as AI-related.

Table 1. Terms marked with a section symbol (§) were classified as ambiguous and required the presence of a second AI-related term to identify a grant as AI-related. Stemming was used on some terms in accordance with the study by the European Commission (e.g. Neural net*).

Key terms by research domain

Within all identified AI-related grants, the most prevalent key terms are “machine learning”, “artificial intellig*”, “deep learning”, “neural net*”, and “computer vision”. This is likely due to their breadth since most of these terms represent a collection of concepts, techniques or applications, rather than a specific method. The following figures show the top 10 most prevalent key terms for SSH, MINT and LS grants over time. We did not include multi-domain grants in these visualisations, as they are more heterogeneous.

In SSH, after “artificial intellig*” and “machine learning”, the most frequent key term is “natural language processing”, followed by “deep learning”, “data science”, “reinforcement learning”, and “neural net*” (Figure 3). It is not surprising that natural language processing is highly used in SSH disciplines, given that this method can be used to analyse large corpuses of text.

Looking at the summaries of the identified SSH grants, we find that they often fall into one of two categories. Some apply AI or machine learning methods to answer research questions. For example, in a grant awarded in 2020, the researchers are mining a corpus of electoral programmes using natural language processing to identify how identities of political parties can evolve over time. Other AI-related grants in SSH investigate how the development and deployment of AI impact society. For example, based on analysis of documentation combined with a survey and expert interviews, researchers in a grant awarded in 2024 are aiming to understand how public administrations use AI in their administrative practice and to evaluate the conditions under which citizens and experts support such usage.

If a key term drops out of the top 10 temporarily, the line becomes transparent until the key term once again enters the top 10.

In MINT, the most prevalent key terms we identified are “machine learning”, “neural net*”, “deep learning”, “computer vision”, “artificial intellig*”, “reinforcement learning”, and “data science”. Many grants, particularly within engineering sciences and mathematics, develop AI systems or technologies, such as machine learning methods. Grants within MINT that do not themselves develop AI methods generally apply these methods in different disciplines to analyse data, to make simulations, to process images or to improve the capabilities of robots, for example.

In LS, the most frequent key terms are “machine learning”, “artificial intellig*”, “deep learning”, “neural net*”, “reinforcement learning”, “computer vision”, and “pattern recognition” (Figure 5). Many of the identified grants apply a wide variety of machine learning methods to analyse data and images to answer specific research questions, to develop diagnostic tools and therapeutic interventions and to predict treatment outcomes. While the focus in these grants is on the application of AI to answer research questions, there are cases in which the research findings feed back into the further development of such methods.

A strong basis for further analyses

We see that funded research related to AI increased considerably across all research domains, especially over the last eight years. In the process, we have described an approach based on searching grant applications for a set of AI-related key terms to identify AI-related research at the SNSF. This method has been widely used by research organisations and in bibliometric studies to provide an overview of the field of AI and its development. The adopted approach is transparent, reproducible and scalable. For example, new key terms can be added, or the approach can be applied to other data such as publications. Due to the rapid evolution of AI, our list of key terms will require periodic updating to include the latest developments. Furthermore, the set of key terms can be strategically adapted in order to answer new questions.

Using a static list of key terms has drawbacks. Their selection naturally influences the identification of grants, and no choice of key terms will perfectly identify all grants related to AI. In a preliminary analysis, we compared three different key terms lists and refined our approach to maximise the inclusion of AI-related research while keeping the false positives low. Nonetheless, AI-related grants that do not use any of these key terms in their titles, keywords or summaries will be missed. Due to different uses of AI across different research domains, it is unclear whether the approach is comparable for all research domains. While the approach is useful in identifying research that is related to AI, more detailed analyses of the grants would be required to better understand the role of AI in each grant. However, we are convinced that this approach provides a strong basis to identify research related to AI at the SNSF and further analyse its content.

The SNSF will use this approach to develop a better understanding of AI-related research, which will be helpful in tailoring its application and evaluation processes. This will also allow us to monitor the outputs of such research. Beyond these analyses, the SNSF is monitoring national and international developments on AI in research to be prepared to adapt to relevant changes in the research landscape.

What type of data did we use?

The basis for this analysis was all the grants written in English from Project and Career funding awarded between 2011 and 2024. The sample includes a total of 21,784 grants. We included all variables necessary to identify the grants and to perform the key term search as well as some further information: title, keywords, summary, grant number, funding scheme, research domain and disciplines.

To analyse the occurrences of the different key terms, we quantified the number of grants in which each key term occurred. Each key term was only counted once per grant. Thus, even if a term appeared multiple times, for example in the title and summary of a grant, it was only counted once.
